c++怎么读取用逗号分割的文件

Question

比如这样的文件，怎么读到一个二维数组里呢

Answer 1

FILE *f;
f=fopen("data.txt","r")
if (NULL==f) {printf("Can not open file data.txt!\n");exit(1);}
char ln[80];
int data[2][3];
int i;
i=0;
while (1) {
 if (NULL==fgets(ln,80,f)) break;
 if (3!=sscanf(ln,"%d,%d,%d",&data[i][0],&data[i][1],&data[i][2])) printf("Format error on line %d:%s",i+1,ln);
 i++;
 if (i>=2) break;
}
fclose(f);
